MECHANICAL Movement- SPECIFICATION forming part of Letters Patent No, 453,903, dated June 9, 1891. Application filed September 29, 1890. Serial No. 366,510. (No model.)

To all 1071/0772/ t may con/ecrit:

Be it known that I, ISRAEL F. GOOD, of Al lentown, in the county of Lehigh and State of Pennsylvania, have invented a new and Improved Mechanical Movement, of which the following is a full, clear, and exacti description.

My invention relates' to improvements in mechanical movements; and the object of my.

1o invention is to produce a simple, durable, and mex-pensive mechanism by means of which power maybe eiiicicntly transmitted and speed greatly increased.

To this end my invention consists in eerx 5 tain features of construction and combinations of parts, which will be hereinafter fully described, and then pointed ont in the claims.

Reference is t0 be had to the accompanying dra-wings, forming a part of this specification,

2o in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is aside elevation of the device embodying my invention. Fig. 2 is a vertical eross-section of thev same on the line 2 2 of Fig. l. Fig. 3 is a sectional plan view on the line 3 3 of Fig. l with the upper-gear 1neehanism removed. of the upper gear and its connected parts on the line 4 4 of Fig. 2, and Fig. 5 is a side ele- `3o vation showing the mechanism duplicated in order to greatly increase the speec.

The device is' provided with a frame A,

which is preferably vertical and which is provided at top and bottom with the cross-pieces 3 5 A and A2, respectively. The lower crosspiece A2 is provided with laterally-extending arms o., having vertical posts a' thereon, and

the said crosspiece is also provided with shoulders a2, corresponding in height to the 4o height of theposts a' and arranged at right angles to the same. A'vertical shaft B extends through the 4cross-piece A2, the lower end of the shaft being provided with a suitable driving-pulley B', although a gear-wheel may besubstituted, if desired. The shaft B has a recess Z1 in the upper end, and fixed to the upper end of the shaft is a gear-wheel i, having teeth .upon its upper side near the outer edge.

-5o A vertical post D is vmounted above the Fig. 4 is an inverted plan shaft B so as to align therewith, and the lower end of the post is provided with a tenon d, which fits in the recess b of the shaft B, and thus serves as a guide for the shaft and also serves to strengthen the post. The post is supported in aixed position by means of the bars d', which are [iz-:ed to the post and extend radially therefrom, the outerends of the bars being secured te the top ot' the posts a and shoulders a2.

A collar Alocsel y eneircles the post D, said collar being pivoted to the post by means of the pins e, which are fixed to the post and are journaledin opposite sides of the collar, so that the collar may rock upon the pins.

A gear-wheel F loosely encircles the collar E, the said gear-wheel having teeth n pon its under side, which mesh with the teeth of the gear-wheel C. The gear-wheel F has more teeth .than the gearwheel C, and is eut away at the parts f so that it may fit upon the bars d and may rock in the man ner described below without interfering with the bars. The gear-wheel F is pivoted to the collar E by the pins f', which are fixed to the collar and turn in the gear-wheel, the pins f being arranged at right angles to the pins e, by which the collar is pivoted to the post D, so that the gear-wheel F rocks in the opposite direction from the collar E, and the gear-wheel and collar being pivoted in the manner described form practically a universal joint.

The gear-wheel F is provided with upwardly-extending arms F', which converge toward the top and are uni-ted to form the block F2, `which is provided witha removable cap F, and the cap has centrally thereon a ball gf A wheel Il pivoted on the under side of the cross-piece A,the trunnion or shaft Il of the wheel extending upwardly through the cross-piece, and on thevlower side of the wheel is a cup 7L, eccentric to the axis of the wheel, and `which tits over the ball g on the cap F5, thus forming an ordinary ball-joint. A gear-wheel J is fixed to the upper end of the shaft il', and power may be taken fror; this gear-wheel, or a pulley may be substituted, if desired.

The operation is as follows.' Then power is applied to the pulley li', the shaft 13 and 1 ill gear-wheel (v revolve und the teeth. ol the geur-wheel i`iiueshiug with the upper geuru wheel ll, actunte said gear-wheel, und :is soon its Seid upper gear-wheel moves the upper ends of the arms F :ire tilted, thus moving the bloei; 'Fi and imparting motion to the wheel ll and gear-wheel .'I'. As soon as the wheel li, starts it changes the position of the geur-wheel F by menus et the connection between the gear-wheel and the said wheel li, the geer'whcel end causing the c teeth thereon to be clinnged, and. it u seen tiret only lthe teeth on one edge of the gear-wheel D Will engage the teeth of the gcnr-whccl C et it given time; but es the position of the gear-wheel constantly changing it will rock ou the pins f and at the seme time the collar E will rock on the pins c, thereby permitting ot' the neceesery movement in the gear-wheel F. A slight movement oi the geztnwheel C und of the wheel F serves to impart e complete revolution to the wheel H and gear-Wheel J, so that e complete revolution of the pulley E and gear-wheel C will impart many revolutions to the wheels H and J, and consequently the device furnishes n very simple menne for multiplying speed and for trousmitting power. It the speedis not suiicently increased by the use of e single device, as described above, it 1n ny loc duplicated, as shown in Fig. 5, in which ense the treme A5 is made tailer than the freine A, and the upper-gear mechanism, comprising thcpoet D, collar E, und geenwheel E and its connected parts, is arranged :there the geur-Wheel J so that the gee-rnvheei in will mesh therewith, and it will rendilgy be seen that the parte nia-y be dupliceted indefinitely until the desired speed is' obtained.

Having thus fully described my invention, I claim en new and desire to secure by Lettere iPnientM `l. A mechanical movement comprising :t ireme,n vertical shaft mounted therein and provided ut its upper end with :t geur-wheel, n post secured above scid gcnrorhecl und supported by radially-exiending bars, at gear wheel meshing` with the lower geur-wheel and connected to the post by e universal joint, Said upper gear-wheel having recesses tofit over the radially-extending bars, as shown, tud having upon its upper side converging arms terminating in t head or block, and n wheel fixed to :t shaft and pivotelly connected with scid head or block, substantially as dcscribed. I

El. The combination, with the revoluble vertical shaft having it gear-wheel fixed to its upper end and the post supported above the gear-wheel and aligning with the shaft, of a coller encircling the post and pivoted thereto on opposite sides, n gear-wheel pivoted to the collar :it right angles to the post-pivots, seid gear-wheel. meshing with the lower gear-wheel and having converging arms upon its upper side which terminate in zt head or block, andn wheel fixed to esuitnble shaft and pivotally connected with seid heed or block, substantielly as described.

3. A mechanical movement comprising n frame, zt vertical shaft mounted therein and provided nt its upper end with n gear-wheel, n post secu red above the geftnwhecl and having it depending tongue projecting into areecss in the vertical shaft, :t collar encircling the post and pivoted on opposite sides thereto, a gear-wheel encircling the collar and pivoted thereto, the pivots being at right angles to the poscpvots, seid gear-wheel meshing with the lower gear-wheel and having upon its upper side converging arms which terminate in a head or block, and :t wheel fixed to t suitable slut-ft and pivotnlly connected with said head or block, substnntiell y as described.
